“…In particular, genetic information can be key when conservation efforts are made to ensure the survival through time of natural populations and the processes in which they are involved (Supple and Shapiro, 2018). The response of individual organisms to changing environmental conditions can be challenging, and their acclimation and adaptive potential are conditioned by their genetic makeup (Fitzpatrick and Edelsparre, 2018). Given the uncertainty of future environmental conditions, as well as the lack of clear knowledge regarding the link between genes and phenotypes, it might be a safe bet to direct conservation efforts to ensure the preservation, when detected, of distinct intraspecific lineages (Moritz, 2002), particularly in a geographic area where climatic fluctuations modeled current genetic features of the local fauna.…”

Genetic information on species can inform decision making regarding conservation of biodiversity since the response of organisms to changing environments depend, in part, on their genetic makeup. Territories of central-southern Chile and Argentina have undergone a varying degree of impact during the Quaternary, where the response of local fauna and flora was rather species-specific. Here, we focus on the sigmodontine rodent Abrothrix hirta, distributed from 35° S in Chile and Argentina to northern Tierra del Fuego. Based on 119,226 transcriptome-derived SNP loci from 46 individuals of A. hirta, we described the geographic distribution of the genetic diversity of this species using a maximum likelihood tree, principal component and admixture analyses. We also addressed the demographic history of the main intraspecific lineages of A. hirta using GADMA. We found that A. hirta exhibited four allopatric intraspecific lineages. Three main genetic groups were identified by a Principal Component Analysis and by Ancestry analysis. The demographic history of A. hirta was characterized by recent population stability for populations at the northernmost part of the range, while southern populations experienced a recent population expansion.

“…Hard red winter wheat, grown throughout the Great Plains and parts of the US Pacific Northwest and milled into flour for bread, is the biggest US wheat class, typically representing ~40% of total US wheat production. Further, human-induced climate change is causing rapid variations of global temperatures and extreme fluctuations in precipitation (Fitzpatrick and Edelsparre, 2018). These changes impose greater pressure for both the crops and breeders, forcing organisms to adapt and breeders to deviate from the established optimal.…”

The Plant Genome W heat breeding has progressed dramatically in the last century thanks to the combination of various technologies (Poland et al., 2012); taken together these advancements have driven the yearly genetic gain through selective breeding to nearly a linear increase of 1% in the potential grain yield (Bassi et al., 2016). Faced against human population growth and uncertain climates, global wheat production, however, still falls short (Curtis and Halford, 2014), as the global demand for wheat is projected to increase 60% when the population reaches 9.8 billion by 2050 (Alexandratos and Bruinsma, 2012). The emphasis now is increasingly not only meeting the food

“…Second, we developed a powerful framework for linking individual variation in dispersal strategy with the environment. Understanding how such components can lead to population-level dispersal is valuable because individual differences in behaviour are increasingly linked with important ecological and evolutionary processes such as habitat fragmentation (Cote et al 2017), climate change (Fitzpatrick and Edelsparre 2018), and biogeography (Canestrelli et al 2016). In fact, individual variation in behaviour has recently been referred to as a 'pacemaker' of evolution of non-behavioural traits.…”

Dispersal is fundamental to life on our planet. Dispersal facilitates colonization of continents and islands. Dispersal mediates gene flow among populations, and influences the rate of spread of invasive species. Theory suggests that individuals consistently differ in dispersal propensity, however determining the relative contributions of environmental factors to individual and population-level dispersal, represent a major challenge to understand the spread of organisms. To address this, we conducted a field experiment using Drosophila melanogaster. As proxies for individuals with different dispersal propensities, we used wildtype strains of flies with natural variants of the foraging gene, known to influence dispersal in laboratory and field experiments. These included flies with fors alleles known to be less dispersive, flies with the forR alleles which are more dispersive flies as well as an outbred population established from field collected flies. We released approximately 6000 flies of each strain in an experimental arena (100 m × 100 m) in the field and our recaptures were used to determine dispersal of flies over time. To estimate environmental effects on dispersal, we measured temperature, wind direction and wind speed. Using partial-differential equations we combined ecological diffusion with advection to estimate dispersal rates and responses to wind. We found that temperature effects elicited a similar response in high and low dispersal lab strains with dispersal rate increasing with temperature most rapidly at temperatures above 18°C. This was in contrast to outbred flies which remained unresponsive to temperature changes. We also detected a response to wind with advection rates increasing linearly with wind speed for all flies in general. Our results suggest that response to temperature and wind can minimize known differences in behavioural predispositions to disperse. Our results also suggest that the direction and magnitude of wind may play a key role in the colonization and distribution of fly populations. Our findings therefore have implications for forecasting the spread of pests and invasive species as well as pathogens and vectors of disease. Our findings further contribute to the understanding of how the environment can modify behavioural predispositions and to influence population-level dispersal in fly populations in particular and insect species in general.
